Witness Daphne Knowles, a retired research scientist at the Ministry of Defence, said she knew immediately "something was wrong".

She said: "The plane looked like a business jet and it was flying too fast and too low to be able to land at Blackbushe Airport.

"It just dived down towards Blackbushe and the next thing I saw was a huge column of thick black smoke.

"At first I thought it was a fighter jet because of the loud noise it was making and also because it was moving at such a high speed.

"It was flying with its engine screaming and very fast – I knew straight away that something wasn't right."
